Three species of lichenicolous Opegrapha s. lat. are newly described, all apparently host-specific at genus level. Opegrapha arthoniicola Coppins & S. Y. Kondr. is described from western Britain and Ireland, where it grows on the thallus of Arthonia radiata on Corylus bark; it has small clustered ascomata, asci that are usually 6-spored and rather small ascospores (10.5–)12.5–14.5 μm in length. Opegrapha sawyeriana Coppins occurs on the thallus of Coniocarpon cinnabarinum, also on Corylus bark, from oceanic western parts of Scotland, Ireland and southern England; in comparison to O. arthoniicola it has smaller, often scattered ascomata with a pigmented basal layer, 8-spored asci and slightly larger ascospores 13–14.5(–16) μm in length. Opegrapha hochstetteri Coppins has been found on thalli of Verrucaria hochstetteri and V. muralis on calcareous rocks and stonework in southern England and Luxembourg; collections were formerly identified as Opegrapha rupestris Pers. but it differs from this species by narrower ascomata with a persistent narrow slit, normally 6- rather than 8-spored asci and ascospores with pigmentation in the spore wall rather than the perispore. Lifted from synonymy is Opegrapha opaca Nyl., which inhabits the thallus of Verrucaria nigrescens and V. viridula on calcareous rocks and stonework, and is so far recorded from southern England, Luxembourg, France, northern Spain and Israel. The hosts of the European species of lichenicolous Opegrapha on Verrucaria s. lat. on calcareous rocks (O. hochstetteri, O. opaca and O. rupestris) belong to different phylogenetic lineages within the Verrucariaceae. A key is also provided to the lichenicolous species of Opegraphaceae currently known from Great Britain and Ireland.

Opegrapha s. 地衣类植物的注意事项。纬度 （Arthoniales）在 Arthoniaceae 和 Verrucariaceae 上，具有英国和爱尔兰地衣 Opegraphaceae 的钥匙

三种地衣歌剧s。纬度 是新描述的，在属水平上都明显是宿主特异性的。油菜花Coppins 和 SY Kondr。描述于英国西部和爱尔兰，在那里它生长在放射蒿在榛属吠; 它有小的簇状子囊，asci 通常有 6 个孢子，子囊孢子相当小（10.5–）12.5–14.5 μm。油菜Coppins 发生在朱砂, 也在榛属树皮，来自苏格兰、爱尔兰和英格兰南部的海洋西部；相比O. arthoniicola它有较小的，通常散布的子囊，有着色的基底层，8个孢子的子囊和稍大的子囊孢子，长度为13-14.5（-16）μm。大花草在 thalli 上发现了 Coppins疣状疣孢菌和五、壁画在英格兰南部和卢森堡的石灰岩和石制品上；收藏品以前被认定为番荔枝个人。但它与该物种的不同之处在于具有持续狭窄狭缝的较窄子囊，通常为 6 个而不是 8 个孢子的子囊，子囊孢子在孢子壁而不是周孢子上有色素沉着。脱离同义词是欧巴卡Nyl.，栖息在黑疣和V. viridula在钙质岩石和石制品上，迄今为止在英格兰南部、卢森堡、法国、西班牙北部和以色列都有记录。欧洲地衣的宿主歌剧在疣状疣s。纬度 在钙质岩石上（O. hochstetteri,奥帕卡和O. rupestris) 属于不同的系统发育谱系疣孢科. 还为地衣类植物提供了一把钥匙苦参科目前已知于英国和爱尔兰。
